- Abstract
- Jefferson Lab-CEBAF. Measurement of the cross section for the exclusive reaction E- P --> E- PHI P using the PHI --> K+ K- decay mode. The data were collected with a 4.2 GeV electron beam on a 5 cm liquid hydrogen target and cover the Q**2 range from 0.7 to 2.2 GeV**2 and W from 2.0 to 2.6 GeV
